Words which, without calling objects or signs, indicate them belong to pronouns. And only in the context of the offer of a pronoun receive a concrete lexical meaning.
From the school program it is known that pronouns happen generally - subject, generally - qualitative and generally - quantitative and also are divided into personal pronouns, returnable and possesive. But in artistic speech sometimes some pronouns are used instead of others. So, in works it is possible to meet the use of a pronoun "we" instead of author's "I" ("In the house of the inspector which we already mentioned …"). For giving of the speech of solemnity the replacement of pronouns with "I" on "we" occurred in ancient texts (royal manifestos). The pronoun "we" in certain cases gives to the speech colloquial character, at the address to the second person ("Well as we feel?"), sometimes it is used for giving of the speech of an ironical shade.
The pronoun "you" can express a politeness form at reference to one person. Personal possessive pronouns in the text practically always lose the value of accessory to the first person, and get new, not connected with a concept of accessory ("Did not pass also month, and my Mikhail was already in love").
The pronoun "such", besides the main functions, in artistic speech gains the value indicating big degree of a state or quality ("It such unfortunate"). The derivative form of this pronoun "such is" is used very seldom, and only as a predicate ("With it there was a cheat such is"). The pronoun "itself" except that it matters "independently, without someone's help", can gain value of the strengthening word ("Here he costs with a rifle"). Pronouns "whose" "how many" it is often used in book language, in the poetic speech, giving it solemnity, pomposity, grandiloquence ("About you, whose memory bloody …"). In terms of semantics, pronouns are words with the changing concrete contents depending on the subject, a context.
